A nurse is collecting data from a newborn who has respiratory distress syndrome and is experiencing respiratory acidosis. Which of the following risk factors predisposes the newborn to respiratory difficulties?
Small for gestational age.
Maternal history of asthma.
Ventricular septal defect.
Cesarean birth.
The Correct Answer is A
Choice A reason:
Small for gestational age (SGA) newborns are at risk for respiratory distress syndrome (RDS) and respiratory acidosis because they have immature lungs that produce less surfactant, which is needed to keep the alveoli open and prevent atelectasis. SGA newborns also have less glycogen stores, which can lead to hypoglycemia and impaired oxygen delivery to the tissues.
Choice B reason:
Maternal history of asthma is not a risk factor for RDS or respiratory acidosis in the newborn. Asthma is a chronic inflammatory disorder of the airways that affects the mother, not the fetus. Maternal asthma can cause complications such as preterm labor, preeclampsia, or intrauterine growth restriction, but it does not directly affect the fetal lung development or function.
Choice C reason:
Ventricular septal defect (VSD) is a congenital heart defect that causes a hole in the wall between the ventricles of the heart. This can result in increased pulmonary blood flow and pressure, which can lead to pulmonary edema and heart failure in the newborn. However, VSD does not cause RDS or respiratory acidosis, which are related to lung maturity and surfactant production.
Choice D reason:
Cesarean birth is not a risk factor for RDS or respiratory acidosis in the newborn. Cesarean birth can increase the risk of transient tachypnea of the newborn (TTN), which is caused by delayed absorption of fetal lung fluid. TTN usually resolves within 24 to 48 hours and does not cause a significant acid-base imbalance in the newborn.

Correct Answer is ["A","C","D"]
Explanation
Choice A reason:
Swimming is one of the best exercises for pregnant women because it provides moderate aerobic conditioning with minimal stress on your joints. It also supports your increased weight and helps you stay cool and comfortable.
Choice B reason:
Scuba diving is not a safe exercise for pregnant women because it poses a high risk of injury to the baby. The baby has no protection against decompression sickness and gas embolism, which are caused by changes in pressure underwater.
Choice C reason:
Walking is a great exercise for beginners and can be done throughout pregnancy. It improves your cardiovascular fitness, strengthens your muscles and bones, and helps prevent excessive weight gain and gestational diabetes.
Choice D reason:
Yoga can be beneficial for pregnant women as it can improve flexibility, balance, posture, breathing and relaxation. It can also reduce stress, anxiety and back pain. However, some yoga poses may not be suitable for pregnancy, so it is advisable to join a prenatal yoga class or consult a qualified instructor.
Choice E reason:
Snow skiing is not recommended for pregnant women because it involves a high risk of falling and affecting your balance. Falls can cause damage to your baby or placenta, especially in the second and third trimesters.
Correct Answer is ["B","C","D","E"]
Explanation
Choice A reason:
Hypertonic is not a type of cerebral palsy, but a term that describes increased muscle tone or stiffness. Hypertonicity can be a symptom of spastic cerebral palsy, which is the most common type of the disorder.
Choice B reason:
Spastic is a type of cerebral palsy that affects about 80% of people with the disorder. People with spastic cerebral palsy have stiff and jerky movements due to increased muscle tone.
Spastic cerebral palsy can be further classified by the body parts affected, such as spastic hemiplegia, spastic diplegia or spastic quadriplegia.
Choice C reason:
Hypotonic is a type of cerebral palsy that affects muscle tone and posture. People with hypotonic cerebral palsy have low muscle tone or floppiness, which makes them appear limp and relaxed. Hypotonic cerebral palsy can affect the whole body or specific parts, such as the trunk, limbs or face.
Choice D reason:
Ataxic is a type of cerebral palsy that affects balance and coordination. People with ataxic cerebral palsy have difficulty with precise movements, such as writing, buttoning a shirt or reaching for a book. They may also walk in an unsteady manner or have problems with depth perception.
Choice E reason:
Mixed is a type of cerebral palsy that includes symptoms of more than one type of the disorder. For example, a person with mixed cerebral palsy may have both spastic and dyskinetic movements, or both ataxic and hypotonic features. Mixed cerebral palsy is usually caused by damage to multiple areas of the brain.
